Los Angeles County sheriff’s detectives are investigating an assault on a 12-year-old middle school boy in Calabasas who may have been targeted after a Facebook group urged students to beat up redheads, a sheriff’s official said today.

The boy was kicked and hit in two separate incidents on the campus of A.E. Wright Middle School in Calabasas by as many as 14 of his classmates, Lt. Richard Erickson said. The students who participated in the attack may have been motivated by a Facebook message telling them that Nov. 20 was “Kick a Ginger Day,” Erickson said, but had few other details about the message.

The incident occurred about 8:30 a.m. Friday. The boy sought help from the school nurse, who contacted the principal. Sheriff’s officials arrived on campus shortly afterward.  “He was accosted by seventh- and then eighth-graders,” Erickson said. “He was kicked and hit with fists in various areas of the body.”

No arrests have been made yet. Detectives are investigating the incident as a possible assault with a deadly weapon. Erickson said he didn’t believe that the boy’s injuries were serious enough to require hospitalization. The victim's name was not released because he is a juvenile.
